Dear Andrew,
we made some efforts to make everything work on Windows, but
unfortunately so far we couldn't find volunteers with access to a
Windows development machine willing to try it out and sort out the
remaining issues. If you could help us with this effort, I'm sure other
Windows users would appreciate it, too. The relevant link to the issue
tracker is:

Cheers,
Malte
